ABIJAH BENJAMIN BENNETT, OF OPELIKA, ALABAMA.

BALING-PREss.

To all whom it may concern:

Beit known that I, ABIJAH BENJAMIN BEN- NETT, a citizen of the United States, residing at Opelika, in the State of Alabama, have invented certain new and useful Improvements in Ealing-Presses, of which the following is a specification.

The invention relates to baling presses for hay or similar material.

One object of the invention is to provide an improved machine of the character named having simple and efficient mechanism for operating the press plunger by motive power, said plunger operating mechanism being of such a nature and the other parts of the machine being so arranged that with but lfew changes the press may be readily adapted for manual operation.

Another object of the invention 4is to provide improved mechanism for feeding and packing the hay or other material into the baling chamber.

A further obj ect of the invention is the pro vision of novel means for regulating the degrec or amount of compression of the material'so that bales of substantially uniform hardness or density may be formed.

Other objects and advantages will appear from the annexed detailed description.

An embodiment of the yinvention comprises the construction and arrangement of parts, hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the claimshereto appended.

in likereference characters designate corresponding parts throughout the severalviews, 1 designates the compression or baling chamber of the press comprising side frames 2, and top and bottom plates 3 securely tied together and supported in a horizontal position rom a base 4 by standards. The baling chamber is provided with a feed opening 6, and arranged to reciprocate in the baling chamber beneath the feed opening, is a plunger 7, to the front face of which is secured a washer plate 8, and which is also provided with a deflector board 9 secured to the upper edge thereof. Detachably secured to the baling chamber above the feed-opening 6 by clamps 10, is a ho per 11, the inner walls of which are providedp with downwardly and inwardly inclined fingers 12 to prevent the material from being forced upwardly from the hopper.

The material is packed into and fed to the baling chamber from the hopper by an oscillatory rake device consisting of a U-shaped frame 13, formed with bearings 14 to engage a rod l'mountedin the forward pair of standards 5. The front wall of the hopper is partly removed and the forward portions 16 of the arms of the frame 13 extend within the hopper and constitute rake bars. .The rake bars, which have a slight downward curve, and are pointed at their ends, are provided with rake teeth 17, extending at right angles to the rake bars and pivotally connected thereto. The rake teeth are free to swing downward, but they are limited in their upward movement to the plane of the rake bars by shouldered portions 18 at their inner ends. The shouldered' portions engage the rake bars when the rake teeth are in the plane of the rake bars, and they are normally held in this position by springs 19, which permit the rake teeth to yield in a downward direction. The rear end of frame 13 is bent downward at an angle to the rake bars and is connected by a link 2O to a short rod 21, carrying the plunger so that, when the plunger is reciprocated, the frame 13 is oscillated, the rake bars moving upward in the hopper on each forward movement of the plunger and moving downwardly on each return stroke of the plunger to feed the material from the hopper to the baling chamber in advance of the plunger. It will be understood that upon the downward movement of the rake bars, the rake teeth are held rigid and act to feed the hay,

but that upon the upward movement, they yield downwardly to permit the ready passage of the rake through the hay.

For the purpose of retaining the hay in the baling chamber in its compressed condition after each forward stroke of the plunger, l provide rigid fingers 22, secured to the forward pair of standards, and projecting within the baling chamber from opposite sides thereof, the plunger being provided with slots 23, so that the fingers 22 do not interfere with the operation of the plunger. For the same reason I also provide the side walls of the'baling chamber with inclined lugs 24.

Mounted in the plunger rod 2l is a roller 25, which rides on a forward extension ofthe bottom plate of the baling chamber, and serves to support the plunger clear of the bottom plate, thereby insuring the free and easy movement of the plunger. The axle 26 of the roller 25 projects a short distance from opposite sides of the plunger rod 21, and the lower end of link 20 makes its connection with the plunger rod through the axle 26, whereby any back pressure due to the feed rake will not force the plunger' rod out of alinement.

Referring to the arrangement illustrated in Figs. l and 2, the plunger rod is connected to one arm of a lever 2-7 by links 29, loosely engaging the axle 26, and secured to the lever by a removable pivot pin 30. A pitman 31 connects the lever and a reciprocatory shaft 32, the movement of which is transmitted to the plunger rod. The shaft 32 slides in a frame 33, which is held fixed from movement relative to the base 4 in any suitable manner and comprises guide members 34 and a guide bar 35 for the shaft 32, said shaft being provided with a recessed portion 36 arranged to slide beneath the guide bar 35. Mounted for rotation on a vertical stud secured to the frame 33 is a disk 39, provided with two tappets yor pins 4040 which project downwardly from the under face of the disk and are diametrically oppositely disposed. A bar 41, which is laid on top of the disk 39 and securely bolted thereto, carries at its outer ends, which extend beyond the edge of the disk, pins or tappets 42 and 43 adapted, when the disk is rotated to successively engage a cam edge 44 of a member 45, pivotally secured to the frame 33. The member 45 is also provided with a cam edge 46 for engagement with a pin 46, secured to the shaft 32, so that when the member 45 is engaged and swung forward by the pins 42 and 43, the shaft is moved forward. The shaft is reciprocated in the reverse direction by the pins or tappets 40, 40 successively engaging a lateral projection 48 of the shaft supplied for this purpose, the shaft being recessed at 71V adjacent-the projection 4S and the recessed portion 36 of the shaft being provided with a curved end wall 38 to permit Y, the ready travel of the tappets 40, 40 transversely of the shaft. The opposite end wall of the recessed portion 36 is straight and arranged parallel with the guide bar 35, with which it is adapted to contact, acting in unison with the projection 4S, which is adapted to engage one of the guide members 34, to limit the rearward movement of the shaft 32.

50 designates actuating levers for the disk 39 pivotally secured thereto intermediate their ends and adapted to have horse power applied to their outer ends to exert a pull or push on the levers as hereinafter more fully set forth. rThe pivots 73 for the actuating levers are arranged near the periphery of the disk at opposite sides of the bar 4] the sides of which are adapted to all'ord contact surfaces, raised above the top of the disk, for the inner ends and intermediate portions ol` the actuating levers, in transmitting motion to the disk. By this arrangement the actuating levers, which are provided with antifrietion devices 50 to engage the upper snrtrated in Fig. l of the drawings with the inner ends of the levers engaging the bar 4l or so that portions of the levers intermediate their ends engage the bar 41. at the ends center of rotation of the disk. By this change, which may be quickly and easily effected by removing the levers and reversingr the position thereof or by swinging the levers around on their pivots, the manner of applying the horse power as well as the degree of leverage can be varied.

As illustrated in Fig. 5, the machine may be readily adapted for manual operation b v removing the hopper, and mounting a hand lever 51, between the forward pair of standards 5, and changing the forward connection of the links 29 from the angle lever 27, to the hand lever. Secured to the haling chamber is a spring to serve as a cushion for the rear end of the hand level', which is weighted. to normally maintain the front end of the lever in an elevated position. The baling chamber is provided with a door 52 to close the rear end thereof, and I provide means whereby the door will be held in a closed position until the amount of compression reaches a certain predetermined point. The door 52 is hinged at 52 to swing downwardly, and is provided with a transverse cleat 54. The rear pair of standards 5 are formed with mortises 55, in which are arranged pins 56. 57 is a U- shaped member, which is provided with hook-shaped portions 5S, and to which is pivoted a bail member 59. The door being in a closed position, the hook shaped portions 5S are inserted in the mortises, and engaged with the pins 56, and. the locking bail adjusted to bear against the door above the cleat. The door 52 is provided with a recess,

face of the disk, may be positioned as ilhisthereof at points further removed from the lill) anti-friction roller of the p .the adjustment of the weight 61 along the scale lever, the door is forced partially open and the rear end of the lever elevated, which acts as a signal to the attendant to remove the bale from the baling chamber. As will be obvious this arrangement provides for regulating the degree of compression, so that bales of substantially uniform hardness and density may be formed, and the character of the bales in this respect may be varied. The plunger 7, besides being suplported by the ungerv rod, is further provided with anti-friction rollers 70, operating on the bottom'board of thebaling chamber. The plunger is rovided with transverse grooves a and the sidewalls of the baling chamber are open at b to permit of the passage of the wire carrying needle and wire in wiring the bales. i

As will be apparent it is important to the effective operation of the operating mechanism hereinbefore described, that, in a plying power to the actuating levers for the disk 39., the levers will not bev forced upwardly and the disk twisted or. canted out of its horizontal position. In l order to provide against such a contingency I employ means as illustrated in Figs. 12 and 13 of the drawings for coupling the thills or trees, to which the ho'rses are harnessed to the levers where.- by the thills or trees can have lateral and vertical play relative to the ends ofthe levers and which will tend to prevent the lifting of the levers. With special reference to Figs. 12 and 13 of the drawings, the coupling means comprises a clip 7 4 to embrace an actuating lever and a band 75 to surround and loosely engage the rear curved portion of the thills 76. The clip 74 and the band 75 are adapted to beipivotally connected by a pin or bolt 7 6 passing through apertures in extensions 77 and 78 of the cli and band respectively, the extension 77 o the clip being spaced to receive therebetween the eXtensions 78 of the band.
